Detailed Description

template<int dim>
struct aspect::internal::Assembly::Scratch::StokesSystem< dim >

A scratch object to store all necessary information to assemble the terms in the Stokes equations. We derive the StokesSystem scratch class from the StokesPreconditioner class, because all the objects that are necessary for the assembly of the preconditioner are also needed for the actual system matrix and right hand side, plus some extra data that we need for the time stepping and traction boundaries on the right hand side.

§ face_material_model_inputs

template<int dim>
MaterialModel::MaterialModelInputs<dim> aspect::internal::Assembly::Scratch::StokesSystem< dim >::face_material_model_inputs

Material model inputs and outputs computed at the current linearization point.

In contrast to the variables above, the following two variables are used in the assembly at quadrature points on faces, not on cells.

§ reference_densities

template<int dim>
std::vector<double> aspect::internal::Assembly::Scratch::StokesSystem< dim >::reference_densities

In some approximations of the Stokes equations the density used for the mass conservation (/continuity) equation is some form of reference density, while the density used for calculating the buoyancy force is the full density. In case such a formulation is used the reference density (and its derivative in depth direction) is queried from the adiabatic conditions plugin and is stored in these variables.

§ rebuild_newton_stokes_matrix

template<int dim>
const bool aspect::internal::Assembly::Scratch::StokesSystem< dim >::rebuild_newton_stokes_matrix

Whether the Newton solver Stokes matrix should be rebuild during this assembly. If the matrix does not change, assembling the right hand side is sufficient.
